Traveling-wave valve arrangement

Abstract

For a traveling-wave valve arrangement with a traveling-wave valve and a linearizing circuit arrangement, it is proposed to design the linearizing circuit arrangement and the traveling-wave valve as one constructional unit and, for the thermal protection of the linearizing circuit arrangement in the simultaneous presence of a high permissible temperature of the valve housing, to maintain the circuit arrangement by means of an active cooling element at a nondamaging temperature lower than the one of the wall of the valve or of a common wall. The cooling element is preferably a Peltier element.

What is claimed is:  
     
       1. A traveling-wave valve arrangement comprising a traveling-wave valve and a linearizing circuit arrangement for compensating a phase response of said traveling-wave valve, wherein said linearizing circuit arrangement and said traveling-wave valve comprise one constructional unit and said linearizing circuit arrangement is maintained at a lower temperature than a wall of said traveling-wave valve by an active cooling element. 
     
     
       2. The arrangement according to  claim 1 , wherein said linearizing circuit arrangement is disposed in an electromagnetically screened housing, wherein said electromagnetically screened housing has an outer surface and an interior. 
     
     
       3. The arrangement according to  claim 2 , wherein said outer surface of said electromagnetically screened housing is cooled by said active cooling element. 
     
     
       4. The arrangement according to  claim 2 , wherein said active cooling element is disposed within the interior of said electromagnetically screened housing. 
     
     
       5. The arrangement according to  claim 1 , wherein said linearizing circuit arrangement is disposed proximate to a radiation-generating system of said traveling-wave valve. 
     
     
       6. The arrangement according to  claim 1 , wherein said active cooling element dissipates heat emitted by said linearizing circuit arrangement into said wall of said traveling-wave valve, or into a common wall of said traveling-wave valve and said linearizer when said linearizer and said traveling-wave valve are arranged within a common housing. 
     
     
       7. The arrangement according to  claim 1 , wherein the cooling capacity of said active cooling element can be controlled. 
     
     
       8. The arrangement according to  claim 1 , wherein the temperature of said linearizing circuit arrangement is maintained below 60° C. by said active cooling element. 
     
     
       9. The arrangement according to  claim 1 , wherein said active cooling element is a Peltier element.
